I've set bellow :

export AUDIOPLAYDEVICE="rsnd/5"
export AUDIORECDEVICE="rsnd/4"

and start zoom on chromium, then /dev/dsp4.0
grew. And tested mic by :

% aucat -o tmp/test.wav
% aucat -i tmp/test.wav

My voice sound from my speaker (/dev/dsp5.0) :-)
Thanx Tomasz !!!

BTW mic volume is low and I set sndiod with :

# /usr/local/bin/sndiod -a on -m rec -f rsnd/4 -v 127

but volume not changed. Is there any way to control mic
volume ?
